DEBATE: DIGITAL SLR CAMERAS ARE BETTER THAN COMPACT DIGITAL
Posted by: BLloyd

I am a digital SLR enthusiast - my web site probably gives that away. I think that there are many advantages of digital SLR cameras.
But I also know that there are many features of compact digital cameras that aren't available on digital SLRs.
This debate presents both sides of the coin so that you can make an informed camera-buying decision

All the Yes points
DIGITAL SLR CAMERAS ARE BETTER THAN COMPACT DIGITAL
Built For Speed
It's electronics vs. mechanics.There's a device called a shutter that sits in front of the digital SLR sensor, blocking it from light.When you take a photo, the shutter (made up of two curtains) opens and closes.This is different from a compact camera, where there is no shutter mechanism. In compact cameras, the sensor is electronically activated every time you take a photo.The advantage of the mechanical solution is that it is instantaneous: you press the shutter button and the shutter snaps open.There's never a delay when you want to capture that photo of a lifetime.(www.digital-slr-guide.com)

A Lens For Every Occasion
If I want to take landscape photos, I attach a wide-angle lens. If I want to photograph bugs and flowers, I use a macro lens. When I take photos of my labrador, I use a telephoto lens and can snap shots even when I'm halfway across a field.One camera, tons of lenses.Again, it comes down to speed.Zoom lenses in compact cameras take time to zoom in and out since the zoom is driven by a motor. You manually control the zoom of a digital SLR, and can zoom as fast or slow as you like.(www.digital-slr-guide.com)

High Quality in Low-Light
One clear advantage of digital SLR cameras is that they're able to capture photos even when there's not a lot of ambient light.So what? Every camera can take a photo when there's not a lot of light - just turn on the flash.Here's the trick: digital SLR cameras can do it without the flash.Digital SLRs are able to take photos when there's little available light because of a feature called ISO: it makes the digital sensor more sensitive to light.While several compact digital cameras will also let you change the ISO of the camera, there is one key difference.As you increase the ISO (and increase the camera's sensitivity to light) you also add grain or "noise" to the image.The advantage of digital SLR cameras when it comes to ISO is that even at high ISO settings they produce very little noise. I can't say the same about compact cameras.If you really enjoy taking photos when there's not a lot of light, the image quality of a digital SLR will exceed a compact any day of the week.(www.digital-slr-guide.com)
Any camera can make correct exposures in low light settings. Aside from having adjustable film speed, virtually every Compact Digital camera available has adjustable shutter speed and aperture size. Also, since the noise inherent in higher ISO's is the result of the film or digital sensor's sensitivity to light, high ISO exposures taken on a DSLR are every bit as noisy as high ISO exposures taken on a CD. The graininess has nothing to do with the type of camera.

You Have Control
This is my favorite advantage of digital SLR cameras.I don't like a machine to be making decisions for me. While it's right most of the time, it isn't right ALL of the time. The human brain will always be better at judging a scene then a camera set to automatic.With a digital SLR, you have complete control over every photo you take, and don't have to rely on the camera to make choices for you.Even if you're not ready to make the jump to a fully manual camera, don't be frightened off.Every digital SLR camera lets you use an automatic setting, and provides you with intermediate steps that offer increasing levels of control over your images.(www.digital-slr-guide.com)
DSLR's do present a higher degree of creative control over your exposure, but virtually every single CD camera currently available has a manual setting that allows you control over aperture and shutter speed. The camera only makes your choices for you if you want it to.

Price
Even though the price has been dropping on digital SLRs, they are still significantly more expensive than their compact cousins.An inexpensive digital SLR camera starts around $500 - and that's often without a lens.
Tack on an additional $100 for a kit lens or $500 for a higher-quality zoom.
If you can't fathom spending $800 to $1,000 on a digital camera, then an SLR is definitely not right for you.(www.digital-slr-guide.com)

No Movie Mode
Just like a telescope focuses light from stars a digital SLR camera focuses light on a CCD which converts analog light signal to digital data. Compact digitals do the same job but the lens is much smaller. The main function of the lens is to focus the light for the CCD capture device. A bigger mirror on a telescope increases the amount of light it is able to focus therefore it can see fainter objects. If you measure the amount of light that passes through a digital SLR cameras lens it is much greater than that of a compact camera. This is the most prominent difference between the two types of cameras. It is the size of the hole that captures the light for the CCD which truely is the difference between the cameras and the Digital SLR's win hands down if you compare the potential to capture light. More light means more data when a photo goes digital and even though this data is not represented in the amount of data the CCD captures it is obviously present in the information presented to the CCD. This is the reason the Digital SLR produces superior quality sensitivity therefore superior quality photos. Now being aware that ISO adjustment ranges differ on every camera you might find price compromising this feature of the camera. A nikon D90 has ISO range up to 6400 and the D80 has a range up to only 3200. Digital compacts are seldom found with comparable ISO's due to the small surface area of the focusing lens. Check out what ISO does here http://www.dpreview.com/reviews/nikond90/page20.asp
Right up until September of 2008, this was a huge difference between digital SLRs and compact digital cameras.SLRs are mostly focused on capturing still images, not video.But in September of 2008, Nikon released a camera called the D90 - the first digital SLR that can capture both still photos AND High Definition (HD) video.Hot on the heels of the D90 came the announcement of the new Canon 5D Mark II - the second digital SLR that captures photos and video (also HD).While the addition of a movie mode appears to be an emerging trend in the digital SLR market, the vast majority of old and even new SLR cameras can not capture video.(www.digital-slr-guide.com)

Limited Live View
A Surprising difference between SLR and compact digital cameras is that some SLRs don't have a live preview mode (especially models released prior to 2007).The LCD is only good for reviewing shots that you've already taken - it won't show you the photo you're about to take.This means that you must compose all your photos by looking through the viewfinder.Many newer digital SLR cameras allow you to compose photos using both the LCD and the viewfinder (these are called live view digital SLRs), but they all have one huge limitation: the sophisticated autofocus systems that SLRs are renowned for don't work very well in "live view" mode.For now, live view on SLRs is fine if you to take photos of static subjects, but it's impossible to use for any type of action photography.(www.digital-slr-guide.com)

Size and Weight
If your idea of the ultimate camera is something that fits in your pocket, then forget all about digital SLRs.The most obvious difference between SLR and compact digital cameras (besides price) is sheer size. Even a small-sized digital SLR camera is twice the size and bulk of a compact camera.While there are many new digital SLR models that are more portable (and are easier to travel with) the addition of a lens to your camera ensures that you'll never be able to stow it away in your pants.(www.digital-slr-guide.com)
